A worker who fell 200 feet from a Longview bridge into the Columbia River is presumed dead. The Cowlitz County sheriff's office says another worker saw the man fall Sunday from a platform under the middle of the Lewis and Clark Bridge, which connects with Rainier, Ore.

Coast Guard and boaters who searched the river were unable to find him.

The sheriff's office says the man was described as experienced and safety conscious, and nothing at the scene indicates how he fell.

The Transportation Department says the man was part of a rigging crew that was installing paint platforms.
